Detailed Description

BLAS Level 2 API.

hemv_batched performs one of the matrix-vector operations

y_i := alpha*A_i*x_i + beta*y_i

where alpha and beta are scalars, x_i and y_i are n element vectors and A_i is an n by n Hermitian matrix, for each batch in i = [1, batch_count].

Parameters
[in]handle[rocblas_handle] handle to the rocblas library context queue.
[in]uplo[rocblas_fill] rocblas_fill_upper: the upper triangular part of the Hermitian matrix A is supplied. rocblas_fill_lower: the lower triangular part of the Hermitian matrix A is supplied.
[in]n[rocblas_int] the order of each matrix A_i.
[in]alphadevice pointer or host pointer to scalar alpha.
[in]Adevice array of device pointers storing each matrix A_i of dimension (lda, n). if uplo == rocblas_fill_upper: The upper triangular part of each A_i must contain the upper triangular part of a Hermitian matrix. The lower triangular part of each A_i will not be referenced. if uplo == rocblas_fill_lower: The lower triangular part of each A_i must contain the lower triangular part of a Hermitian matrix. The upper triangular part of each A_i will not be referenced. As a Hermitian matrix, the imaginary part of the main diagonal of each A_i will not be referenced and is assumed to be == 0.
[in]lda[rocblas_int] specifies the leading dimension of each A_i. must be >= max(1, n)
[in]xdevice array of device pointers storing each vector x_i.
[in]incx[rocblas_int] specifies the increment for the elements of each x_i.
[in]betadevice pointer or host pointer to scalar beta.
[in,out]ydevice array of device pointers storing each vector y_i.
[in]incy[rocblas_int] specifies the increment for the elements of y.
[in]batch_count[rocblas_int] number of instances in the batch.
